For DD's first birthday we're expecting 25 adults and 15 kids between the ages 1-5. I'm deciding between a 10" round cake (3 layers) which they say serves about 25 people or and 12" round cake that serves around 35 people. In the past I've always gone with the 12" round but I always end up having a ton of cake leftover. This time I'm leaning towards the smaller one but then I'm worried it won't be enough. What size cake would you go with?
